neowin.net have a quick review of HPs X310 Data Vault.
Before we go further into the review, let me explain my reasoning for how I reviewed this device. The biggest reason you would want an HP Data Vault is to backup your critical files and software. While this is generally easy to test locally, I wanted to test a real life usage scenario. A test where you are out in the field and your worst nightmare happens, an entire system crash. I put myself in a situation where going back to the office to recover the files is not an option, a true in the field restore and recover stress test…
…Despite having a slower CPU than the X510, it doesn’t seem to suffer as you might expect and its suffice to say that it’s adequate for the job.
